1. Working voltage: 5V-12V (the sound will be significantly reduced when the voltage is lower than 5V [below 3.6V is only suitable
for signal pre-amplification and cannot drive the speaker], the limit voltage cannot exceed 15V);
2. Working current: 1mA (static) to 350mA (max);
3. Output speaker impedance: 4 ohms-32 ohms (high impedance, high sound, high efficiency, if you are not confident in your own
speakers, you can buy the speakers sold in this store, the sound is very loud), (supported speaker impedance does not mean that it
can be released If the sound is loud enough, it is generally recommended to add a power amplifier to increase the output power);
4. Supported speaker power: 0.5W-25W (in fact, any power speaker can be used, the volume has nothing to do with the speaker power,
as long as it is greater than the rated value of the power amplifier output, the loud speaker may be louder), ( Supported speakers
The power does not mean that it can emit a loud enough sound, it is generally recommended to add a power amplifier to increase the
output power);
5. Output power: rated 750mW, instantaneous value 1.5W (max);
6. Volume: 22.7 (length) mm*13.5 (width) mm*7.4 (height)
7. It is used as a microphone preamplifier. The noise and AC ripple are very low. The output signal voltage is greater than 1V. It
drives the power amplifier signal to be strong. If the requirement is not high, you can directly drive the speaker external
amplifier. If you need high power output, you need Rear-stage external power amplifier board;
8. For the sound source of the record player, please check the pickup type of the record player by yourself. This module only
supports piezoelectric ceramics and electret stylus, other stylus is not guaranteed to support;
9. The default gain: 100db, the potentiometer gain is adjustable: 0 to 100db continuously adjustable, modify the ADD gain
capacitor gain can be modified from 20db to 200db;
Package include:
5x module
